For many people, the only time they’ve heard of typhoid has been in historical accounts of grim 1800s-era pioneers becoming infected on their way to the American west, or perhaps through the cautionary tale of Typhoid Mary, who refused to wash her hands, and spread typhoid through her cooking so frequently that she was banished to an island for the remainder of her life.
Despite this reputation, typhoid very much remains a threat today. While rare in industrialized countries, typhoid fever is a significant threat in some low-income countries and should be taken as a risk when traveling.
If you are preparing for international travel, especially to areas where food and water safety may be uncertain, knowing how to avoid typhoid before your trip can help protect your health. Typhoid precautions often include pre-travel counseling, safe food and water habits, hand hygiene, and a discussion with a travel medicine provider about whether a typhoid vaccine is recommended for your destination.
Quick Answer: How to Avoid Typhoid While Traveling
To help avoid typhoid while traveling, schedule a pre-travel health consultation, ask whether a typhoid fever vaccine is recommended for your destination, drink bottled or properly treated water, eat food that is cooked and served hot, avoid unsafe ice or raw foods, and wash your hands often.
A vaccine can help reduce risk, but it does not replace careful food and water precautions. Travelers should still be cautious about what they eat and drink, especially in regions where typhoid fever is more common.
An Overview
Typhoid fever is a bacterial infection caused by Salmonella typhi. The only way to know if a person is ill with typhoid is to have their blood or feces tested for this bacterium.
Symptoms of typhoid are like those of other common gastrointestinal illnesses and usually develop one to three weeks after exposure to the bacteria. They range from mild to severe, and often include fever, headache, nausea, constipation or diarrhea, loss of appetite, and a rose-colored rash on the body.
Transmission is via the fecal-oral route, meaning that contaminated feces and sometimes urine may enter water supplies or food supplies, which may then be consumed by and infect others. Salmonella typhi lives only in humans; there is no animal reservoir for the bacteria.
It has previously been estimated that worldwide there are up to 22 million new cases of typhoid fever and 200,000 deaths each year. More recent global estimates from the World Health Organization report about 9 million cases and 110,000 deaths annually, showing that typhoid remains a serious global health concern even as estimates and surveillance methods change over time.
Most cases are confined to the developing world, where the disease is endemic, with the greatest burden being in the Indian subcontinent and in Southeast Asia.
Regions with the highest incidence of typhoid fever, greater than 100 cases per 100,000 persons per year, include south-central Asia and Southeast Asia. Regions of medium incidence, about 10–100 cases per 100,000 persons per year, include the rest of Asia, Africa, Latin America and the Caribbean, and Oceania, except for Australia and New Zealand. In Delhi, India, the incidence of typhoid fever has been reported as 9.8 cases per 1000 people per year.
Who Should Be Concerned About Typhoid Before Travel?
Travelers should take typhoid precautions seriously when visiting areas where sanitation, clean water access, or food safety may be unreliable. Risk can be higher for people visiting friends and relatives, staying for extended periods, eating local or street foods, traveling to rural areas, or visiting places where typhoid fever is known to occur.
You may want to speak with a travel medicine provider before your trip if you are traveling to parts of Asia, Africa, Latin America, the Caribbean, or other destinations where typhoid exposure is possible. The right prevention plan depends on your itinerary, medical history, travel length, activities, and how soon you are leaving.
Available Typhoid Vaccines and Vaccination Campaigns
Two typhoid vaccines are licensed for use in the United States; these are typically reserved for people traveling to areas where typhoid fever is common or for people who may come into direct contact with the disease.
Ty21a is a live, attenuated vaccine given in oral capsule form. Within the first two years of vaccination, the vaccine is moderately effective at preventing disease. Three years after initial vaccination, the vaccine offers no protection. The minimum age for this vaccine is six years.
Vi capsular polysaccharide, also known as ViCPS, is an injected subunit vaccine. In clinical trials, it reduced disease rates by nearly 66%, though effectiveness wanes after several years. The minimum age for this vaccine is two years.
When Should You Get a Typhoid Vaccine Before Travel?
If a typhoid vaccine is recommended for your destination, timing matters. Travelers should schedule a pre-travel appointment as early as possible so there is enough time to review vaccine needs, medications, and other health precautions.
The injectable typhoid vaccine is typically given at least two weeks before possible exposure. The oral typhoid vaccine is taken as a multi-dose series and should be completed before travel according to medical guidance. If you were vaccinated in the past, ask your provider whether you need a booster before your upcoming trip.
Because vaccine recommendations can vary by destination and health status, the safest approach is to review your travel plans with a qualified travel medicine provider before leaving.
Typhoid Precautions for Food and Water Safety
While vaccination at a traveler’s clinic is a highly effective method for preventing typhoid, avoiding exposure altogether is another essential measure. Typhoid spreads from contaminated food and water, so practicing the same precautions as you might to prevent foodborne illness can be effective.
Investigate the restaurants you may be visiting. Have there been any cases of typhoid in the area nearby? Do locals eat there? Contamination can occur if a chef does not wash their hands properly after using the restroom, so ensure the facilities offer such sanitation. Be sure to wash your own hands before your meal as well.
When it comes to food, a common mantra is “Cook it, peel it, or forget it.” Avoid fruits, vegetables, or other foods which are uncooked and cannot be peeled, and if you are eating hot food, be sure it is served to you steaming-hot. The high heat should have killed any bacteria in the meal.
Bottled water can also be a safer source than tap water, with bottled carbonated water being the safest. If you must drink tap water, boiling it for 1 minute should help kill any bacteria.
Practical Food and Water Tips to Help Prevent Typhoid
To reduce your risk while traveling, keep these typhoid precautions in mind:
- Drink sealed bottled water, boiled water, or properly treated water.
- Avoid ice unless you know it was made with safe water.
- Eat food that is cooked thoroughly and served hot.
- Avoid raw fruits and vegetables unless you can peel them yourself.
- Avoid unpasteurized dairy products.
- Wash your hands before eating and after using the restroom.
- Use hand sanitizer when soap and clean water are not available.
- Be cautious with street food if sanitation is uncertain.
- Avoid food that has been sitting out at room temperature.
These steps are especially important because typhoid vaccines are not perfect. Even vaccinated travelers should continue using safe food and water practices throughout their trip.
Symptoms of Typhoid Fever After Travel
Typhoid symptoms may appear after you have already returned home. Because symptoms can look similar to other gastrointestinal infections, it is important to tell your healthcare provider where you traveled and when symptoms began.
Contact a medical provider if you develop symptoms such as:
- Fever
- Headache
- Nausea
- Abdominal pain
- Diarrhea or constipation
- Loss of appetite
- Weakness or fatigue
- Rose-colored rash
- Symptoms that appear one to three weeks after possible exposure
Do not ignore persistent fever or stomach symptoms after international travel. Testing may be needed to determine whether typhoid or another travel-related infection is present.
